“…However reports on synthesis of fluoride nanoparticles are limited. CaF 2 nanoparticles were synthesized by different methods such as sol-gel method [11][12][13][14][15][16], solvothermal process [17,18], reverse micelle method [19,20], different precipitation methods [21][22][23][24], and flame synthesis [25]. Chemical co-precipitation is a simple method to synthesize fluoride nanocompounds.…”

“…Above all, the luminescent [7,8], scintillation properties [9,10] and applications to the solar cell [11] have been studied for Eu doped CaF 2 single crystal. In our previous work [5], Eu-doped CaF 2 synthesized by the sol-gel method exhibits weak and sharp luminescence due to the typical intra-transitions of 4f electrons of only Eu 3+ ion. In order to apply intense luminescence due to f-d parity allowed transition, easy reduction process from trivalent to divalent Eu ions can be expected considering the lowest reduction potential (Eu 2+ /Eu 3+ = 0.35 V) [12] in all rare earth ions.…”

“…A number of researches have been reported to focus on the synthetic methods and characterizations of rare earth fluoride and rare earth doped alkaline-earth fluoride using the HF [1], trifluoro-acetates [2][3][4][5] and 1,1,1-trifluoro-5-methyl-2,4-hexanedione [6]. Above all, the luminescent [7,8], scintillation properties [9,10] and applications to the solar cell [11] have been studied for Eu doped CaF 2 single crystal.…”

“…Wide-band-gap fluoride CaF 2 provide attractive hosts for those rare earth (RE) ions that are capable of producing fast and efficient emissions under ionizing irradiation [2,3,4,5]. Doped phosphors such as CaF 2 :Eu and MgF 2 :Eu have been investigated as efficient lu minescent materials with potential applications in solid state lighting, fiber amplifiers, solid s tate lasers, and radiation detection [6,7]. CaF 2 :Eu 2+ is one of the earliest known thermo lu minescent materials and was among the earliest used for TL dosimetry [8].…”
